FIELD OF THE INVENTION

The invention relates generally to an apparatus for cooling an electronic component and, more particularly, to a set of housings enabling the construction of a compact water-cooled cold plate with an integrated pump having high performance and reliability.

BACKGROUND OF THE INVENTION

With the recent onslaught of improvements in computer technology, the thermal load generated by personal computers has increased considerably. In order to ensure proper operation of the heat generating devices in the computer including, but not limited to, central processing units, video graphics processing units, and memory modules, liquid cooling systems have become widely used as a means to effectively dissipate the heat generated by these components. As the complexity of the liquid cooling systems increases, there also exists a need to simplify such systems.

One type of cooling system employs a cold plate that is attached to a housing to form a cavity equipped with one or more inlet and outlet ports to circulate a coolant inside the cavity. The cold plate may be machined so that one of its faces forms a plurality of pins or fins. Such a device is also known as a water-block. A recirculation pump provides circulation of the coolant inside of the water-block. Water-blocks and pumps are separate units. Examples of pumps are found in U.S. Pat. Nos. 6,736,616, 6,713,918, and 6,897,596 B2.

An inlet fitting 216 is attached to an inlet port 223 of the serialization housing 15 by mean of a chemical or other bonding method or the like. An outlet fitting 221 (FIG. 9) is attached to an outlet port of the serialization housing 15 by means of a chemical or other bonding method or the like, thereby providing an egress path to the coolant flow to a heat exchanger that may be located downstream of the cooling apparatus 10. The inlet port 223 of the serialization housing 15 directs flow to an apex of a flow inlet cavity 219 of the coolant flow control housing 14 as described in greater detail below.

The length of the flow outlet port 226 is at least equal to about 50% of that of the pins 118 of the cold plate 17, thus providing a distributed flow path onto the pins or fins 118. A flow outlet cavity 220 of a generally rectangular shape includes a flow inlet port 228 of rectangular shape the length of which is at least equal to about 50% of that of pins 118 of cold plate 17. The primary function of the coolant flow control housing 14 is to provide a distributed flow path over the plurality of pins 118 of the cold plate 17.

The coolant flow control housing 14 has a generally square shape featuring four or more feet extending at or about the corners or other areas of the housing 14 so as to provide a retention mechanism to attach the cooling apparatus 10 to an electronic component such as a central processing unit. The coolant flow control housing 14 may have a length and a width of between about 50 mm and about 70 mm.

FIG. 13 is a partial cross-sectional perspective view of the cooling apparatus 10 of FIG. 1 illustrating the cooling fluid flow path from the device inlet and up to the device impeller 203. The cooling fluid enters the device inlet fitting 216 of the serialization housing 15, travels and fills the inlet flow cavity 219 of the coolant flow control housing 14, enters the flow outlet port 226, where it is then distributed over/through the plurality of protrusions—i.e. where it travels through the pins or fins 118 of the cold plate 17. The cooling fluid then enters and fills the flow outlet cavity 220 through the inlet port 228 of the coolant flow control housing 14, and egresses through the pump inlet port 224 of the serialization housing 15 to the pump impeller 203.

FIG. 14 is another partial cross-sectional perspective view of the cooling apparatus 10 of FIG. 1 illustrating the cooling fluid flow path from the pump impeller 203 and up to the device outlet fitting 216 of the serialization housing 15, where the cooling fluid enters the impeller inlet port 205 of impeller 203, is distributed and propelled by centrifugal force through the channels created by blades 206 against the circular walls of hydraulic cavity 225 of the serialization housing 15, enters the outlet port 222 of the serialization housing 15, and exits through the outlet fitting 216 of the serialization housing 15 towards a heat exchanger that may be located downstream of the cooling apparatus 10.
